To all whom it may concern:

Be it known that I, ROBERT J. CHIPNLAN, of the city of Paterson, eounty of Passaic, =and State of New Jersey, have invented a new and useful Improvement in Artesian Welle, of

which the-following is a speeification.

In'sinking-Artesian wells water is sometimes obtaiied in a sufficient quantity from a gravel bed, or froma stratum of rock, and the object of my nve'ntin is to provide a means for obtainin g and utilizing eith eror both of these wa-- tersuppiies when desiredr I aeeonpiish this p bymeansof the tubing and plug hereinafter described. I- am aware that in the Sinking of Artesian wellsthatperforated pipes having openings orslots of various dimensione have .bee'used and that numerous eontrivances have been nvented to prevent these openings from' being stopped u p orciogged by sand' .er small gravel. In the ordinary Artesian weil sunk into a. gravel bed, the bottom of the pipe is either drawn to a point or a conieal I ;metal plug is Secured to the "bottom thereof which makes it difficult to drill deeper if deof a wooden plug. Frequently in sinking Arte'sian wells 'an outside pipe is first driven and then a perforated pipe inserted and the first pipe withdrawn. The elogging or stopping of these perforations is sometimes pre-- ventedtby means 'of a screen of some description. I do away with all screens by having my pipe slotted as hereinafter described and object is acconplished by drilling into the' rock and lowering an inner pipe, not perforated, and of the const'uction hereinafter described and shown in the drawigs.

I n the acconpanyin g drawings, which form a part of this speeiication, and in which simisired. This diflicnlty I overcome by the use Fig. 2 is a side elevation of thesane,

'part sectional, showing an inside pipe not perforated andan inside bevel shaped eoilar inside of' the coupling which eoniects the ion-. ,gitudinally slotted section of pipe with'the ad- `joining section of pipe. Fig. 3 is a part setional side eievation showing the longtudfinally slotted p`pe provided at its lower end "With a weoden plug; i In the drawings -A-is the lengitudinally :slotted pipe.

4 -B--represents the longitudinal Slots.

.-C- and -C'- are the couplings.

;slotted pipe. E is the inside pipe. u

-'G-- is a collar inside of the conphng .-O-, in Fig. 2,'and 11- is the wooden plug in the bottom of the longitudinaily slotted 'pipe -A-.

In ail the views the letter --a-- represents ;a stratum or bed of gravel and theletter -b-' alayer of rocks. The inne' pipe -E-' is 'ests upon the bevel shaped collar --G-, and is provided with an inwardly projecting flange -F-, all around its upper edge, The part -C'-- may be a steei. shoe or an ordnary coupling of any suitable material.

` My method of Sinking an Artesian well to ebtain a supply of gravel'bedwater is to drive the iongitudinaiiyslotted pipe -A-- into the earth, then connect another section' of pipe -D- by a coupling -C--, drive that in and so on, keeping the earth out of said pipe,until the stratum of gravel is reaehed, when a suflieient supply of water can 'be obtained. I thus obtain a goodsuppiy of gravel-bed wa.- ter without the expense and labor of first driving in an outside 'pipe,inserting the perforated pipe and. then withdrawing the outside pipe., Provided I do not wish to go to rock, having obtained a su iicient supply of water in the gravcl-bed, I insert and drive down to the bottom of the longitudinally slotted section of pipe, the wooden plug --1I-, which plug will -D- is a section ot' pipe adjoining the in position thei-ein as ..L -;ide o" my pipo a tool provided for su en by reason of the moisture and be'held shown in Fig; 3. In the ordinary Artesian well where a. perforated pipo s now in use, it is next to impossibie to drili in the rock if it is'desired to obtain a.-

supply of rock water, because of the' sond w hich is adnitted through 'the perforated ppe. In case I wish to go deeper and enter the rock to get rock water, I overcome the obstacie which is offered by the send, as foilows: With my tools I pieree the wooden plug, iu-. se't the iuuer pipo E which shuts out the wa ter or send which may possibly have entered ihre u gh the elongated Slots LB- into the sietted pipe- A-, and then driil down inside of the i u n erpi pe-E- th rou go therock, assh own in Fig. 2. It Iwish to obtain only a, supply of rock water the, inner pipo E is allowed to remain inside of thelongitudinally siotted pipo :-A the upper bell monthed .portion of said unerpipe E restig on :me being supported by the bevcl shaped coilar-G-, shutting off the supply of gravel bed water as shown' in Fg. 2. If however I wish to obtaiu a supply of both gravei-hed and rockwater I drop'inthat purpose which enteriug theiunerpipe E engages the iuwardiy p-ojecting fiauge '--`F- on the upper end of said innerpipe E and I lift said muer pipe E clear out of the well aitogether. Then 1 will have asuppiy of water [rom the hoie drilled in the rock as weii as a suppiy from the gravel-bed ti'rough my longitudiualiy siotted pipe '-A-. It is obvious therefore that Icon insert a wooden plug into my slotted pipe at anytage of the work inot-derr to test or ascortain the amount of waterI oln ohtein; and it" the supply is not sufficient I cau pierce and shiver n y wooden plug and ;so ou eiking my pipe until I reach a, stratum of rock as shown in. the drawing& W'hen my ppeiis aii driven :my ordinary pipe 'may be attoched.

`With the eiongated slot arrenged l as shown it is next to impossible for the'water to be shut off by means of Sander gravel. \Vith this description of my invention, what I desire to secure by Letters'Patent is 1. The eonbination of a. longitudiually Slot- .Lted pipo, no two elougated slotsadjoining 'each other throughout theirwhoie length, and a wooden plug at the bottom of said longtudinally siotted section of pipo, coustructed suhstantizlly as shown and set forth and for the purpose specified.

2. The combiuation of& metal pipe provided with longitudina i Slots, no two siots adjoining each other throughout their entire length, an adjoiuiug section of pipe, a coupliuz for counecting said siotted pipe with said adjoiu- 'ing section of pipe,`a collatinside of said coupiing and between the djoining sections of pip,`said collar being hevel shapedand au 'inside metal pipo made bell mouthed ot it's upper end and provided with an inwardiy projecting flange, eonstructed substautiaiiy as and for the purpose specified. i

" The conbination of& metal pi pe provided with iongitudinaisiots, no two slots adjoining throughout their entire length, an adjoin ing section of pipe, a coupiing for conneotng said slotted pipe with said adjoining section of pipo, a collzr inside of said coupling and hetweethe said' odjoining sections of pipo, said coila r being bevet shaped, and :m inside 'metal pipo' made he1i`mouthed at its' upper end adapted to .rest upon and he supported by said bevel sheped collm', and provided with :Lu iuwardly projectig fimgo, and a, woodeu plug at bottom of slotted pipe, all coustructed substantinily as shown and set forth and for the purpose specified.
